SPECFICATION forming part of Letters Patent No. 394,352, dated December11, 1888.

Application filed September l0, 1888. Serial No. 285,028. (Model.)

To LIZ uf'tom it may con/cern.:

Be it known that l, \\"ILLIA \I ll. FYE, a citizen of the United States,residing at Chicago, in the county of (look and State of' Illinois, haveinvented a new and useful Windowrlightenera of which the f'ollown is aspecift cation.

My invention relates to eontrivances for tightei'iing windows; and itconsists of two narrow metal plates, one to be screwed fast to thestop-bead of? a window-frame, at the edge of' the saine next to thesash, and made with flanges at its edges extending in oppositedirections, and a hole somewhat. above its middle point for the passageof' a rivet, the other with a slot made lengthwise for the passage ofsuch-rivet, a flange on its outer edge, and a thuinlrpieee on itsbroader end. The construction and application of such contriv ance areillustrated in the accompanying drawings, in which-- Figure l is anelevation ol a portion of a 'window frame and sash embodying my invention. Fig. 2 is a cross-section off the same, taken on. the line l l ofFig. l. Fig. 3 is a detail plan section ofi' the same, taken on theline2 2 of Fig. Fig. al. is vanV edge elevation of my tightenel.' detached.Fig. 5 is a front elevation ofi' the saine. Fig. f5 is a similar viewshowing the wedge part i'n a lowered position as compared with Fig. 5.

Similar letters refer to si milar parts throughout the severa-l views.

In the drawings, A is a plate screwed fast to the stop-bead C next tothe sash C. 1t is made with the flanges A and A2 at its edges, extendingat right angles to the plate, but in opposite directions. The edges of.the plate make a small angle to each other. The flange A passes betweenthe stop-li)ead and the sash, and thus aids the screws (ly in holdingthe plate firmly in position.

B isa rivet passing' through the plates A and D, but leaving a spacebetween its head and said plates snfiicient to permit the plate D to bereceived therein with room enough to move freely.

D is a wedge-shaped plate made to fit tightly between the flange A2 andthe sash C. This plate is made with the flange A3. extending atright-angles from the edge next the sash. and Y curved slightly inwardat its extremitv next to the narrower end of the plate. The edge of' theplate next to the flange A2 is in a straght line throughout its entirelength. This flange is designed to prevent the plate from wearing agroove in the sash and to aid in holding the sash firm when tightened.The plate D has a slot, D, ruiming' lengthwise parallel with the flangeA2 when the sash is tightened by the action off the plate. Through thisslot the rivet B passes, the slot bein made of such width as to permitthe plate D to slide up and down. At its lower end the plate D isprovided with a thumlrpieee, D2. The plates are seeured to the stop-beadC a little distance below the middle rail, c, so that the lower sash, C,when pressed by the plate D,\vill force the upper sash, ("2, against thewindow-box, and thus both sashes be tightened. The plates are placedwith their narrower ends upward, and a pair off plates is secured tocach stopbead.

The manner of. using the tightener is obvions. The plates being secured,as above indicated, the thumb and finger are applied to the piece l)2and the plate D is fforeed up ward. Owing to its wedge-like shape, itwill, as `it moves, press the lower sash more and more tigl'ltl)`against the upper sash, and that against the win low-box, and thustighten both without absolutelvv locking them.

My invention is not intended to be a window-fastener-neither lock norsuppmt. It

designed to tighten windows, so as to prevent rattling and to shut outdust, noise, smoke, cold air, the., and to secure sash against movingwhen weights and windows are not perf'ectlgv balanced.

ll'aving nowdescribed in v invention, whatl elaim as new, and desire losecure by Letters Patent of the United States, is-

ln a sash-securer, the combinationof the base-plate A, with its flangeA2 at right angles to the plane ol' the same, the plate lf), with itsflange A3, with slot l)3 parallel to the flange A2, and thun'llrpieceD2, and the rivet- B, secured .in the plate A, all substantially as setforth.
